Just happened to go to the Pumpkin Masters website (Zombie Pumpkins is still the best!) and found out that they have some free patterns that are available to download. Check out the ones that they have up right now.
They're actually all pretty cool except for Flack Jack which seems pretty generic to me. Also if you check out Pumpkin Masters facebook page and "like" it you can view an additional 6 patterns. I won't spoil those for you so go check them out on facebook and see if there are any that strike your fancy!
